vThe yWater heater :comprises a .casing or clarlfibervQ` .of any. suitable form,.butpref-L erably cylindrical and verticallyelongatedi offthe steam boiler withthe casing or chamber 9, at or near its upperend, is ahot-water-k pipe 10Ahav'inga hand yvalve 11 therein for opening or closing the passage therethrough. Connecting the lower end of the casingbor 13 by means offwhichtheepassage'through the connection of the pipes 10 and 12, to feedk hotwater from the steamboiler to the upper n end of thelchamber-9 and to allow said Water, when cooled in a manner to` appear yherein-- after, to be returned'tothe boiler ata low ypoint throughthe pipe12. A continual circulationof hott waterlthrough the chamber f 9 is therefore provided.'

A pipe 14 connects the water reservoir? 'at a vlow point thereof with `a fittingl securedv radially intor the rchamber 9 atalow point, and 4this Ylitting has k,connected e' thereto vwith- Thee upper end' ofithis coil Ais .connected toa p fitting l`17 radially secured'Withinthechamthe reservoir 7 Water is supplied to the water reservoir 7 by a pipe (not shown), in any suitable manner, and the water within the reservoir is 'fed to the lower end ofthe coil 16 by means of the pipe 14. The water within the'coil is heated by the hot water circulating through the chamber 9 and pipes 10 and 12, and as the water in the coil lbero-mes Vheatedv it ascends and passes into the water reservoir 7 through pipe 18. A hot-water supply pipe "19 is connected to pipe 18,- and through aportion of the latter-this pipe 19 haseonneetion with All of these parts are now commonly `in use, but the heater diitersa--frornhe commonly known water heater of this type in that its head 2O is provided with an axialssciew threaded opening 21 in which is arranged an internally screw-threadedbushing-or fitting 22.' Into the Lupper portion of this bushling or 'fitting a pipe'123 ,is screwLthreac-ledwhich leadsto thetop ot the steamfboilerand jhasa water pipe 24 connected therewith.`

"Thew'ater pipe'24is5provided with a`hand valve25 and the pipe`23 is also provided .With ahand .valve 26. The 'head' 2O .is fastenefd `to Vthe upper end ofthe chamber by means of ings 32; or, if desired, anyctypelof opening 1 or openings may providedlin thistu'be for the passa-ge therethrough otstealndelivered ,theeinto from fthe'dome of the steam boiler through the medium of the "pipe 23,." 'Il-his cleaning `tube is readily removable from the chamber and as readily insertable therefinto yit 4bein g simply necessary to disconnect `the pipe 23 from the lbushing or'ittin-g22-and then disconnect the itting from-the 1head20,

whereuponthe cleaningtube 29 can'be withdrawn through Ythe opening'21 iin the shead, thus makingit unnecessary to remove the head from'the chamber. vIn Water heaters of this type the head Aismade solid andm-ust be removed in order to :gai-n access :to the interior ofethe heater. i

u In applying my 4:invention to heaters now in use, 'itismy intention to substitutethe head shownand described for the solidhead genen aljly used, as access tothe interior ofthe cham;

When cleaning the interior of the Water heater, and especially the coil, the valves 11 ter-xediment, ,inorustations or other matteiadhering to the coils, and also the walls of the chamber 9. After a quantity of steam has `gbeen'admittedtoethechamber 9, the valve 34 ,may .be opened, thus allowing the steam to pass with any loosened matter to the sewer.

In the voonstructlon shown V1n Y Figs. I3 and 54, 1the ihead orf cover-vof the casing is voli-somewhat modified V-form, and vin .these rigures 4this headvon covenis shown -hollowso astogprovide a chamber 35 having an inwardly-convexed innerer glower 4wall l36 ,provided with numer; t
